4 Statements The flowing energy on global level is 1000 times the today demand Locally produced bio energy is cheaper than any fossil fuels Burning bio fuel is more fun than fossil fuels Existing energy actors are not taking necessary actions

5 The Ineffective energy system

6 Reach the goals by utilising the losses The today primary energy consumption will be decreased by utilising the losses The losses can only be utilised for low temperature demands Low temperature demands is space heating, drying and evaporation Heat distribution system is the key District heating must be built in Europe as infrastructure

7 Strategic resources for District Heating Geothermal Energy Industrial Waste Heat Energy from Waste Fossil Fuels, for peak load Biofuels Source: Swedish District Heating Association Combined Heat and Power

8 District Heating an integrated part of the energy system Heat market Industrial Waste Heat Bio Fuels Energy from Waste Fuel production Fossil Fuels, peak load ALDE, Worksop on Biofuels Combined Heat and Power

11 Energy consumption in Latvia/person MWh per person One tenth of ha per person Food(vegetable) Food (animal) Heat Tranportation fuel Electricity

12 Latvia opportunities Large amount of district heating Large amount of farming land per person Natural gas dominating fuel today No use of burnable waste today, only landfill Big part of district heating not used for CHP

32 Socio-economic benefits of using bio energy Land owners get long term contracts for energy supply and takes part in the local cooperation Uses the waste products from society as fertilizer Solves nitrogen leakage to recipient Clean farming land from heavy metals Local energy needs society planning Local energy needs local interests/owners
